VXLAN/EVPN – Host routing

In an previous post Advertising IPs In EVPN Route Type 2, I described use cases for advertising IP addresses in EVPN route type 2. Host ARP and host mobility I already covered so today we will focus on host routing.

To be able to show this scenario, I have added another server (SERVER-2) and will be using the topology below:

There is already existing configuration for VLAN 10 (L2 VNI) and for VLAN 100 (L3 VNI) which is shown below:

vrf context Tenant1
  vni 10001
  rd auto
  address-family ipv4 unicast
    route-target both auto
    route-target both auto evpn
!
interface Vlan10
  no shutdown
  vrf member Tenant1
  ip address 198.51.100.1/24
  fabric forwarding mode anycast-gateway
!
interface Vlan100
  no shutdown
  mtu 9216
  vrf member Tenant1
  ip forward

To get SERVER-2 connected the following is needed:

• Configure VLAN 20 and map it to L2 VNI (VNI 10002).
• Make the L2 VNI a member of the NVE.
• SVI for VLAN 20.
• Configure port towards SERVER-2 in VLAN 20.

This is shown below:

vlan 20
  vn-segment 10002
!
interface nve1
  member vni 10002
    ingress-replication protocol bgp
!
interface Vlan20
  no shutdown
  vrf member Tenant1
  ip address 10.0.0.1/24
  fabric forwarding mode anycast-gateway
!
interface Ethernet1/3

Painless Progress with My Ubiquiti Upgrade

I’m not a wireless engineer by trade. I don’t have a lab of access points that I’m using to test the latest and greatest solutions. I leave that to my friends. I fall more in the camp of having a working wireless network that meets my needs and keeps my family from yelling at me when the network is down.

Ubiquitous Usage

For the last five years my house has been running on Ubiquiti gear. You may recall I did a review back in 2018 after having it up and running for a few months. Since then I’ve had no issues. In fact, the only problem I had was not with the gear but with the machine I installed the controller software on. Turns out hard disk drives do eventually go bad and I needed to replace it and get everything up and running again. Which was my intention when it went down sometime in 2021. Of course, life being what it is I deprioritized the recovery of the system. I realized after more than a year that my wireless network hadn’t hiccuped once. Sure, I couldn’t make any changes to it but the joy of having a stable environment Continue reading

netlab 1.7.1: Eye Candy

What do you get when you write code next to a Christmas tree? You can expect to get tons of eye candy, and that’s what netlab release 1.7.1 is all about.

It all started with a cleanup idea: I could replace the internal ASCII table-drawing code with the prettytable library. Stefan was quick to point out that I should be looking at the rich library, and the rest is history:
